OKLAHOMA CITY (AP) — The latest on the scheduled execution of an Oklahoma death row inmate who was convicted of ordering the 1997 beating death of a motel owner but claims he is innocent and was framed by the actual killer. (All times are local):

12:15 a.m. - A death row inmate's scheduled execution for his role in a 1997 motel killing would be the first in Oklahoma since the nation's highest court upheld the state's three-drug lethal injection formula.

Richard Glossip is scheduled to be executed Wednesday at the Oklahoma State Penitentiary in McAlester, despite his claim of innocence. A request for a stay of execution is pending with the U.S. Supreme Court.

Glossip was the lead plaintiff in a separate case in which his attorneys argued the sedative midazolam did not adequately render an inmate unconscious before the second and third drugs were administered.

They said that presented a substantial risk of violating the Eighth Amendment prohibition on cruel and unusual punishment. But in June, the justices voted 5-4 that the sedative's use was constitutional.
